Writes our submitter in Philadelphia: “In our apartment building, packages are left by the block of mailboxes, relatively near where your individual mailbox is. I’ve never had a problem, but apparently not everyone was so lucky…this sign was on every floor of the building.”

“For the past couple of weeks,” writes Anna in Oakland, “someone in the alley or the building next door to mine has started clapping every day at 8:30 a.m. Just clapping. For at least ten minutes at a time. It’s been driving me crazy, and apparently I’m not the only one.”

Sam spotted this somewhat presumptuous notice while house-hunting in South London. “We looked everywhere for the monster cat,” he says, to no avail. (Perhaps if you’d tried slipping a few opened tins of tuna fish in your pockets?)

As part of a lesson about civic responsibility, many teachers encourage their students to participate in letter-writing campaigns to Congress, the school board, the Mayor, or other public figures. (Thanks to the efforts of second-graders in Mission, Texas, for example, Texans can now proudly refer to tortilla chips and salsa as their official “state snack.”)

Meanwhile, this teacher in Ypsilanti, Michigan enlisted her 18 middle-school students in a cause even closer to home — her home, that is — by getting them each to write a persuasive letter asking her noisy neighbor to curb his all-night partying.

If it wasn’t obvious, Lorah in NYC says the response note here was most definitely a total lie. (The residents of 4B are musical theater actors, and sing-and-dance-a-thons are not uncommon events in their apartment.)

David spotted this oh-so-charming scene while cycling through the well-to-do area of Hampstead, London.

Adds David: “The completely knackered fence is in front of an overgrown plot and right next door to a well looked-after house (possibly owned by old folk who are convinced the neighbourhood has gone to ruin.”)

Meanwhile, Alison was a bit perplexed by this note (and the seemingly undisturbed hedge below) in West Hampstead. “I stared at the hedge for ages trying to work out what was wrong with it,” she says. “Finally I just took a picture and ran away.”

Darin in Chicago came across the note on the side of his neighbor’s garage just as he was throwing his own dog’s crap in the trash can. (This is kinda like getting out the new roll of TP, but then leaving it on the side of the sink to get wet instead of just putting it on the dispenser…except, worse.)

I don’t really understand the logic here either, but perhaps this particular dog owner is still dealing with the scars from dealing with neighbors like this one, from Ottawa:
